INSTALLATION INSTRUCTIONS

EB7-4W Module

Clear-Com’s EB7-4W 4-Wire Option module can be added to the KB-702, KB-

702GM, KB-701, and HB-702 products. This option allows the speaker or

headset station to be operated over longer distances than are possible with a

standard Clear-Com intercom line. This option can also be used to connect

with fiber optic transmission equipment. The EB7-4W 4-Wire Option module

connection is a transformer-isolated, audio-only connection and does not

convey the call signal. The module also requires local powering.

Two-channel stations can have two separate 4-wire connections with this

option. The Channel Switch on the front panel selects which channel is

connected.

Installation

The EB7-4W plugs onto one- or two-channel speaker or headset stations as

illustrated in

Figure 1.

Use the following steps to install the EB7-4W Option Module:

1. Remove the two screws from the station’s main circuit board and

replace them with the supplied jackscrews.

2. Remove plugs P1 and P3. Retain these plugs for possible future use.

3. Plug the EB7-4W Option onto the main circuit board where P1 and

P3 were plugged.

4. Fasten the EB7-4W in place with the two screws removed in step 1.

Powering the Station

When the EB7-4W is installed, the speaker or headset station requires local

power, which can be obtained from the following sources:

20-30VDC

A suitable DC source is the Clear-Com 400067Z 30V 500mA AC-DC

converter.

14-20VAC

A suitable AC source is a doorbell transformer. This can be fitted in a

separate box that will contain the power-line connection and the low-voltage

output can be routed to the connector on the EB7-4W circuit board.

Note: Different types of doorbell transformers are commonly available at

hardware stores. Ensure that the output voltage is suitable for use with

the EB7-4W.

Warning: Always follow local electrical codes. Do not install mains wiring in

the same electrical box as the speaker or headset station.

Connect the two wires from the power source to the two-position, plug-on

terminal strip supplied with the 4-Wire Option. Plug this connector onto the

EB7-4W circuit board as shown in

Figure 1.

Wiring the 4-Wire Module

The intercom line connector on the main circuit board does not function when

the EB7-4W is installed. Instead, the 4-wire intercom connections are made to

the connectors on the EB7-4W circuit board. For each channel, “Audio Out”

and “Audio In,” pairs are provided. Both are balanced, 600-ohm connections.

An optional jumper can be installed if the receive signal is noisy. This adds a

resistive termination to the receive Audio In signal, reducing the level by 6 to 8

dB. Typical wiring is as shown in

Figure 2.

Figure 2: Typical EB7-4W Wiring

• 4-Wire Intercom Line Connections: When the EB7-4W is used, the

intercom connections to each channel are made to five-terminal plug-

on connectors on the EB7-4W circuit board instead of to the connector

on the KB-701 circuit board. The connections for each pin are visible

on the circuit board when the connector is unplugged. The connector

pinout for each channel is as follows:

• Pins 1 and 2—Intercom Audio Input (audio to the speaker or

headset)

• Pin 3—Optional Receive Jumper (used if receive signal is noisy)

• Pins 4 and 5—Intercom Audio Output (audio from the

microphone).

When the KB-702 is used, the 4-wire intercom connection must be

made to the Channel B connector.
